1) iCloud (especially photo stream and now Notes/Reminders since they can sync with Mountain Lion)
2) Retina display
3) Apps that make daily tasks easier (banking, movie times, restaurant reservations, sports scores, setting our DVR, etc)
4) Siri (this is probably going to open up a can of worms). I've never had a problem. I use the voice commands constantly when I'm driving and only use Siri for setting the timer.

do i dare say battery performance??? with my screen lit up half the damn day, and all things considered, i have to say it's pretty good

of course we always want more but that's a given no matter what. surely there will be a battery that will last 3-5 days (heavy usage) without a charge... one day *fingers crossed*

For what the iPhone is and does I too find the battery good.

I can remember when I got my first iPhone back in 2009. The last phone I'd had before getting this was a Sony Ericsson K850i, the battery on this was unreal, I could get around 4-5 days easily, but the Sony Ericsson didnt have all the processing power and large screen size of the iPhone.

I think battery tecnology is the only thing that hasn't kept up with smartphone technology, but I think one day, the battery life we see now on smartphones will be laughable.

Yeah I agree iCloud is really useful when you've got other iOS devices and or Macs. I use Siri occasionally but this more due to me living in the UK and been unable (at present) to use local search on web searches, but happily this will change in iOS 6 and I will then use it a lot more.

One of my most used apps is an app that lets me set my Sky tv box to record programmes. I only last night used it to set it to record a programme that I knew I wouldn't be home in time to catch.

I like the whole experience. There seems to be an app for almost everything I want to do. The touch screen and predictive text are awesome. I also love the fact I never have to reboot my phone! It just works.
